Purpose or Objective
Providing patients with access to their medical records
and collecting patient-reported outcomes (PROs) from
them is of interest in modern healthcare. In Radiation
Oncology, no major successes have been reported and the
provision of medical data to patients remains a challenge.
With a patient who is also a computer scientist, a radiation
oncologist and a medical physicist on our team, we set out
to build Opal, a mobile phone app and portal for oncology
patients. Opal will provide patients with:
•
Appointment schedules
•
Check-in/call-in for waiting room management
•
Status of treatment planning/treatment
schedule
•
Access to personal health information (PHI)—
treatment plan, lab results, medical notes
•
Just-in-time educational material, specific to
the patient’s diagnosis, treatment and phase of
treatment
•
Contact information and a messaging system
•
Tools to complete PRO questionnaires
•
Maps and hospital information (eg parking)
Patient's committee module—
Patients for
Patients
Material and Methods
We developed a secure and confidential communication
system that incorporates data from our Aria database
(Varian Medical Systems, Palo Alto, CA), patient
authentication, encrypted data exchange and a cloud
server (Firebase by Google Inc.) external to the hospital.
Figure 1 provides a schematic of the data flow from Aria
to/from Opal.

database by Google.
Results
The design, development and debugging of Opal have been
guided in five ways: (1) a literature review to study
existing patient portals, (2) a patient survey, (3) a patient
focus group, (4) a closed beta-release to non-patient
volunteers, and (5) a pilot to engaged patients who will
provide feedback. Figure 2 provides screenshots of the app
that will be released to our pilot group of patients.

Conclusion
We have developed Opal, a smartphone app and web
portal, for oncology patients at our comprehensive cancer
centre. Opal provides patients with access to their PHI,
appointment schedules, waiting room management,
relevant just-in-time educational material and patient-
reported outcomes
questionnaires.
Development is currently in the closed beta phase with
testing provided by volunteers with fake electronic health
records. We will release the app to a pilot group of
radiation oncology patients in November 20 17, followed
by general release to all radiation oncology patients in
early 2017. Release of the app to all oncology patients is
planned for the spring of 2017.

Republic
Purpose or Objective
National Radiation Protection Institute performs on-site
audits in the Czech Republic. In total, 53 on-site end-to-
end audits for prostate and 16 for H&N/brain radiotherapy
were performed. Prostate case was verified in the national
run for all centres using IMRT in 2013 and repeated for
majority of centres with upgrade/installation of new
linacs in 2014-2016. There was a pilot run with head
phantom in 2016. Majority of results were within
tolerances. All results were analysed to describe the most
interesting findings and the weakest points.
Material and Methods
Absorbed doses with ionisation chambers and plane doses
with EBT3 films were measured in the pelvic or head
phantom. Following aspects can be assessed: unit
calibration, TPS model accuracy for reference field, MLC
accuracy, CT numbers to RED conversion in terms of its
influence to dose, phantom geometrical offset at the
couch, optimisation constraints, radiobiological plan
parameters calculated from DVHs. Anthropomorphic
phantoms (pelvic and head) with benchmark PTVs and
OARs were used. Three sets of audit results were analysed:
prostate audit national run, repeated prostate audit,
H&N/brain audit pilot run. Methodology is applicable to C-
arm linacs, Tomotherapy, Leksell Gamma Knife, and
